How to Measure Toilet Bolt Distance: Common Specifications

As we all know, toilets are essential sanitary fixtures in our daily lives. So, what are the standard size specifications for toilet hole distance? Let's take a closer look.

The common size specifications for toilet hole spacing：

The standard pit distance typically ranges from 30 to 50 centimeters, which is the industry standard measurement. The pit distance should be determined first; otherwise, the toilet cannot be fixed in place. Additionally, the pit distance must take into account the thickness of the bathroom tiles, as otherwise the toilet may not be installable.

The measurement for the toilet is based on the pit distance, which essentially refers to the distance between the drainage hole and the wall. This is generally determined by the size of your bathroom. Therefore, before purchasing a toilet, you should measure the distance between the drainage hole and the wall to the left. If the bathroom has not yet had wall tiles installed, you should also subtract the thickness of those tiles during measurement (usually between 3 to 10 centimeters).

Before installing the toilet, it is crucial to read the product instructions carefully and follow the specified installation requirements. According to regulations, the connection between sanitary fixtures and the water supply and drainage pipes must be tight to avoid leakage. The toilet should be fixed using expansion bolts and sealed with materials like putty or silicone glue. The base should not be fixed with cement mortar, as this not only prevents cracking that could lead to toilet damage but also facilitates repairs in case any problems arise in the future.

How to Measure Toilet Pit Distance：

There are usually two methods for measuring the pit distance. The first method is to use a ruler to measure the distance from the center of the drainage hole to the wall. The second method is to ask neighbors with the same unit type; typically, toilets in similarly designed homes will have the same pit distance.

Of course, before measuring the toilet pit distance, it’s essential to understand the drainage system. After that, you can measure. The drainage pipes typically fall into two categories: horizontal drainage and floor drainage. Horizontal drainage can only accommodate direct-flush toilets, while floor drainage can accommodate both direct-flush and siphon toilets.

In summary：after reading the above information, you likely have a better understanding of standard toilet hole distance specifications. For more related information, please continue to follow our website, where we will present more exciting content in the future.
